cut not counting whitespaces

| Hi,
I have this file wherein i am trying to cut based on characters.
Since the file is a fixed length one, there are spaces present to mark
field start-end. my cut instruction however, does not seem to count the
spaces as characters (i use -c). I also tried -b but to no avail.
I have not yet tried PERL or any other tool... just wondering on
behvior of cut.
Any ideas ?
cheers
raghav..

| try awk, it got more built-in functions, wish it helps.
I am not quite good at it, but it will do what u want i reckon.

Are they spaces? or are they tabs expanding out to spaces?
When counting characters, one tab character can expand out to look
like several spaces.
If your file has mixed tabs and spaces, its probably better to define
the delimeter to be tab and go by fields instead of characters.
Or use awk/perl which would have better field seperation guessing than
cut does.

Have you tried cut with -f and -d' ' ?

I don't use cut much but this sounds like a job for awk/nawk/gawk.
